So far I just ordered linear bearings and holders that I found surplus
in the US. I am looking at a CNC system that is offered by a CNC
retrofit company in Woolongong. They have a developed a servo
controller that runs on step and direction signals. This seems an
afordable way for me to go at present. Though If I really knew my
electronics - which I don't, and thats the problem - I would try for
some more surplus gear that seems relatively cheap for this backyard
builder.

Thanks to all who helped with my enquirees on software for running a
tangential blade machine I am building I have a good start I think
with DANCAM as a free start and Professional sign making software to
look at for serious work.

So, I can get my head around most aspects af the cnc machine but am
pretty hazy re issues around the compatability of cam software,
machine software, controllers servo amps and motors.

For instance Cadlink Profilre lab outputs in HPGL direct to
controllers? So you need controlers that understand HPGL as opposed to
G Code?

Ideally I would like to start trialing my machine with the old DANCAM
shareware which I already have and then upgrade to professional
software when my machine is working and will be ready to generate some
income for me. But again I am concerned about compatability problems.

If any one can help to clear the air on this area or point me in the
direction of some tech info site or something like 'CNC for Dummies' !
I would be most grateful.
